Parameters
| Name | Type | Default | Range | What it does |
|---|---|---|---|---|
| intensity (Can change over time) | number | 0.7 | 0 to 1 | how big and dense the fire is; also raises the town's own smoke a little (see townSmoke)Can change over time |
| at | vec2 | -1330, 1500 | -4000 to 4000 m | where the fire stands, metres along the shore and inland of home's door (used when distance is as-set) |
| distance | choice | as-set | as-set, behind-town, on-the-hills, far-hills | put the fire on the hills: behind-town 600 m inland, on-the-hills 1.5 km, far-hills 3.5 km; as-set uses at |
| columns | integer | 1 | 1 to 4 | how many columns stand along the ridge; more columns leave room for fewer extras (anvil, glow) |
| spread | number | 500 | 150 to 1500 m | the distance between neighbouring columns along the ridge |
| height | number | 700 | 300 to 3000 m | how high a full-strength column climbs above its base before it spreads |
| width | number | 2.5 | 0.5 to 3 | how wide the columns are, as a multiple: 1.5 is a 40 m radius at the foot, widening 0.14 m per metre of height |
| anvil | number | 1 | 0 to 1.5 | how far the pale smoke spreads downwind at the top; 0 leaves the column plain |
| lean | number | 0.35 | 0 to 1.2 | how far the wind bends the column, metres sideways for each metre of height |
| windToward | number | 100 | 0 to 360 deg | the compass bearing the smoke blows toward: 120 is along the shore, 30 inland, 210 out to sea |
| base | number | 100 | 0 to 600 m | how far above the ground the smoke first shows; lift it above the near rooflines so it reads as rising from behind |
| glow (Can change over time) | number | 0.2 | 0 to 1 | how strongly the fire lights the foot orange; faint by default, since a daytime sky washes it outCan change over time |
| fireTemp | number | 1400 | 900 to 2000 K | how hot the flames glow, which sets the orange of the foot's glow |
| smokeColour | color | #3b342f | – | the dark grey-brown of the dense smoke near the fire |
| liftedColour | color | #8f8478 | – | the pale, sunlit tan-grey of the smoke high up and in the anvil |
| townSmoke | number | 0.15 | 0 to 1 | how much of the intensity goes to the town's own smoke field, which veils the whole town; 0 leaves it alone |
| haze | number | 0 | 0 to 2 | the town's haze for the shot, set once as it starts: 0.05 is clear air, 0.3 hazy, 0 leaves it alone |
